Everton have been monitoring the Senegalese striker very closely, especially due to Moise Kean's situation still being very unclear.
However, a report from Le10 Sport has claimed that PSG have enquired about the 19-year-old, seeing him as a potential replacement to Kean.
Sima has scored 19 goals in all competitions this season, with four of those goals coming in the UEFA Europa League, the latest one being at the expense of Leicester City, as the Czech side progressed to the Round of 16 of the competition.
If he continues on his fine run of goals, and if Slavia Prague go even further in the Europa League, then he might become one of the most wanted young strikers in Europe.
West Ham United have also been scouting the striker, as they seek other options in attack, with their only natural senior striker at the club being Michail Antonio, who has been ravaged by injuries in the past.
David Moyes is very keen on bolstering his options in attack, especially if they want to build on this very impressive season, with another great season next year.
The Irons have dealt with Slavia Prague very well in the past, with West Ham buying Tomas Soucek and Vladimir Coufal from the Czech side, with the two of them excelling in London.
With the amount of clubs circling around Sima, it is inevitable that he will move on in the summer, it is only a matter of when.
